TYPEWRITING-MACHINE.

Patented Oct. 19, 1920.

Application filed November 22, 1918. Serial No. 263,646.

To ((7/ whom it may concern Be it known that Rowsiir, a subject of the Emperor of Germany, or a citizen of Germany, but having taken out preliminary United States naturalization papers, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful lmprovcments in T ypewriting-Machines, of which the following is a specih'cation.

This invention relates to typewriting machines and more particularly to tabulating mechanisms therefor.

The principal object of my invention is to provide an improved tabulating mechanism conveniently arranged for operation and 'capable of considerable Hexibility in use.

In the embodiment of the invention herein disclosed, provision is made of denomination-selecting members mounted to move` with the carriage and connected with denominational or decimal stops, so that, by manipulation of a selecting member of the desired denomination, operative positioning of the corresponding stop will be effected.

Further provision is made of means whereby, eoncomitantly with the setting of the denominational stop, ing column-stops will be moved intoposition to enable the stops thereon to be engaged by an operatively .positioned denominationalE stop, and the carriage will be released from control by' the escapement mechanism.

Another feature consists in the provision of means 'whereby the improved tabulating mechanism can' he used for ordinary tabulation. To`this end, provision is made of means for retaining one of said denominational stops in operative position, and of a tabulator key of the usual form for moving the column-stop bar into operative position and concomitantly releasing the carriage. 'ithout a stop held in operative position on the, carriage. the ordinary tabulator key. acting alone, would be effective only to release the carriage.

Other features and advantages will hereinafter appear.

Fig. 5 is a view of the parts shown in Fig. 4, but in operative position for denominational tabulating obtained by advancing one of the denominational-selecting members.

.Character keys 1 acting through intermediate parts, not shown, cause type-bars 2 to be swung against platen 3 supported on a carriage 4 slidably mounted on rods 5 and 6. Said carriage 4 is urged toward the left side of the machine by means of the usual strap 7 and spring drum 8, and its movement under such urging is controlled by the usual escapement mechanism. Operative connection between said carriage 4 and the escapement mechanism is established by a rack bar 9 pivotally mounted on said carriage andv normally meshing with the pinion 1() forming part of said escapement mechanism. Said pinion 10 has a usual one-way connection, not shown, with an escapement wheel 11 which is controlled by means of fast and loose dogs 12 and 13, respectively. Operation of said dogs `12 and 13 to permit movement of the escapement wheel is effected through a movable frame 14 comprising a universal bar 15, which is engaged' by heels 16 on the type-bars 2 during the latter part of the printing stroke.

The machine is also provided with a tabulator key. 17 mounted on a lever 18, which, bv means of a link19 pivotally connected that upon depression of tahulator key-17l motion will be transmitted through the parts y just described to lift rack bar 9 out of mesh with said pinion 10, and thus release the carriage from control by the escapement mechanism.

The mechanism thus far described is well known in the Underwood typewriter.

In the embodiment of the invention herein disclosed, the tabulating mechanism is carried at the front of themachine. To this end, a frame 27 is secured to a projection 28 of the typewriter carriage, and provision, is made of denominational or decimal stops 29 slidably mounted in a slotted bracket 30 secured to frame 27. Direct actuation of said stops 29 is obtained by means of levers 31 pivoted on shaft 32 carried by frame 27, each oi' said levers having at its lower end a pin 33 projecting into a slot 34 at the rear end of the corresponding stop. Each lever is eng-aged by a spring 35, which acts to hold the upper end of the lever against a stop formed in the cover 36 of frame 27. F or moving levers 3l to operatively position stops 29, bars or plungers 37 are `mounted in traine 27. At their rear ends, all of said bars 37 are guided in a slotted portion of frame 27 and are provided with slots 37al through which passes a shaft 38 mounted in 'said frame 27. This arrangement permitsa limited movement ot' said plungers. 1n order to provide sufficient space for the keys 39 carried at the front ends of said plungers, alternate plungers are curved upwardly near their rear ends and then carried forward parallel to the straight plungers. Both sets of plungers have their forward ends guided in slots in plate 40 carried at the outer end oi frame 27 As a result of the different shapes of the rtwo sets 'of plungers 37, the convenient arrangement of keys 39 in two banks is obtained. Each olE said plungers is also provided with a de pending' finger 4l for the purpose to be pointed out hereinafter. v

For coperationvwith stops 29, there are provided column-stops 42 adjustably positioned along a rack 43 having teeth 'at letterspace distances apart. Said rack 43v forms part of the swinging frame which also comprises arms 44 fixed on a rock shaft 45. An arm 46 fixed on shaft 45 is provided at its outer end with a cam slot 47 through which extends a screw 48 supported by atabulator key lever 18. It will be seen that actuation of either shaft 45 or lever 18 will serve to actuate the other.

Mounted on the frame, comprising 'the rack 43, are arms 49 carrying a brake bar 50, which, in coperation with brake block or brake shoe 51 mounted on frame 27, constitutes normally ineffective braking means for controllingr the carriage when released from the escapement mechanism.

It will be seen that upon movement ot' the plunger 37 to operatively position the corresponding denomination-stop 29, the depending finger 4l on said plunger will engage bar 50 and bring the same into operative engagement with brake shoe 5l, at the same time bringing stops 42 into position `to coperate with the operatively positioned stop 29 andeffect the release of the carriage through connections including rock shaft 45, arm 46, and .lever 18.

In ordinary use, stops 42 determine the tabulator column, and stops 29 the denomination in such column, and tabulating action is effected by a key 39. Vith the carriage at any position `in its path, actuation ot' a denominational key will cause coperativu j' positioning of the corresponding denominational stop and the column-stop rack. and. upon release of the carriage, theoperatively positioned denominational stop will move until lit com-es into engagement with the column-stop corresponding to the next tabulating column. The only result of depressing key 17 is to release the carriage 4 l'rom the escapement mechanism. l

Provision is made whereby tabulation in the ordinary way can be effected by depression of key 17. For this purpose, a pin 52 is secured to the rear end of the letthand plunger 37, and another pin 53 to the upper end of the corresponding lever 31. both of said pins extending through -a slot in frame 27 of sufficient extent to permit free movement. These pins are engaged bv a cam-shaped member 54 forming part ot' an arm 55 pivotet at 56 on the frame and provided at its other end with a finger-piece 57. The forward edge 58 of member 54 is 1n the forni of an arc of a circle about pivot, .56 as a center, and, when the lingerp1ecev57 is drawn forward to the Fig. l position` or beyond, Serves to lock pin 52 and the corresponding plunger 37 in torward position. Th'erear edge 59 of' member .54 acts to force pin 53 and the lever carrying the samel to the rear, and to thereby operatively position the left-hand denominational stop. Edge 59 is provided with a depression 60, and at the limit of movement of arm 55, pin 53 moves into said depression and latches the parts in position.

he latching action is such, however, that arm 55 can readilybe depressed by means ot' finger-piece 57. It it evident that with the left-hand denomination-stop latched in operative position, depression of key '1T will -cause coperation of said denominationalstop and column-stops 42, and thereby et'- fect tabulation without` the decimal or de- Variations may be resorted to within the scope of the invention, and port-ions` of the improvements may be used without others.

Having thus described my invention, I claim:
